Question

I am trying to accomplish the following, but with a session variable (ie., ‘session[:dynamically_named]’), rather than an instance variable. This is how I see it can be done with an instance variable:

instance_variable_set("@#{params[:key]}", params[:val])

Seeing how there doesn’t seem to be a “session_variable_set”, how can this be done, even with some alternative work around with a session variable?

Answer 1

You set values on session like you would with an ordinary Hash, e.g.:

session[:dynamically_named] = 'some_value'

# or, to match your example code...

session[ params[:key] ] = params[:val]
